Hi,
I'm trying to deploy a webapp to Tomcat 8.0.39 on CentOS 7 x86_64 that depends
on native shared libraries. I can't install the shared libraries in a
system-wide location because there are multiple applications/webapps being
deployed to this system that use different versions of the same native shared
libraries. We're already running two instances of Tomcat to isolate the
webapps from one another. Here's what's going on:
Tomcat #1 (/opt/tomcatwx) - The webapp described below is able to find all
necessary native shared libraries
bin/setenv.sh source's bin/setenv-wx.sh.
bin/setenv-wx.sh appends
-Djava.library.path=/usr/lib64:/lib64:/lib:/usr/lib:/opt/tomcatwx/lib/gdal to
JAVA_OPTS.
conf/catalina.properties appends
,"${catalina.home}/lib/gdal","${catalina.home}/lib/gdal/*.jar" to common.loader.
lib/gdal contains the following files:
drwxr-xr-x. 2 tomcatwx root 4096 Apr 16 01:06 data
-rw-r--r--. 1 tomcatwx root 134785 Apr 16 00:59 gdal.jar

Tomcat #2 (/srv/tomcat) - The webapp described below is unable to find a native
shared library referenced by the JNI shared library.
Native library load failed.

webapps/myapp/WEB-INF/lib contains the JNI jar:
-rw-r--r--. 1 tomcat tomcat 134646 May 1 14:03
webapps/myapp/WEB-INF/lib/gdal-2.2.2.jar
which references libgdaljni.so
libgdaljni.so references libgdal.so
which references libgdal.so.20
which references libgdal.so.20.3.101632
What have I failed to do that is preventing Tomcat/Java from finding the fully
resolved libgdal.so that is in the same directory where it found libgdaljni.so?
I tried eliminating the symbolic links by copying libgdal.so.20.3.101632 to
libgdal.so, without success.
I tried copying the gdal-2.2.2.jar to the lib/3p directory, without success.
Thanks in advance for any help.
Scott
